Fatal Exception's Neil McAllister gets into the holiday spirit with a post that gives thanks to technical advances for developers, including open source tools, modern IDEs, and distributed version control. 'I'm old enough to remember when performance-critical routines meant hand-coded assembly language and sometimes even keying in machine code as hexadecimal digits. We've come a long way since those bad old days, and not surprisingly we owe a lot of our progress to technology. So for this Thanksgiving, here are just a few of the modern advances for which I, as a developer, give thanks.' What are you giving thanks to?
